First observation is Gates is the #1 receiving threat in SD by far. He is a much bigger threat than Chambers. It will be Chambers leeching off the double teams of Gates (which is like every play) rather than Gates performing better because of Chambers drawing the doubles - Chambers can be covered 1v1 as long as there is possible FS help.
Chambers will give SD a more viable passing threat so LT2 won't see 8 in the box as often - this helps LT2 obviously. One person who this won't help is VJax. You can drop him now, his value is nothing but a small "chance" to catch a TD with Gates > LT > Chambers as the top 3 receiving options. He won't avg more than 30 yards / game rest of this season, you can bet on it. Add on to the fact that Craig Davis is not too bad himself, you can see why VJax's opportunities will be extremely limited. SD will favor its 3 superstars, pushing everyone else into fantasy oblivion.
As for Miami, without out-thinking ourselves, it's going to be all about Ronnie Brown, that's predictable.. RB is the LT of Miami. He'll probably end up leading the team in receptions, and obviously rushing. Booker's value goes up, but not by much. Ginn's value goes up drastically from before. Miami can actually throw the ball this year, and Ginn will draw alot of 1v1 coverage. I think for 2008 draft, Ginn will be considered draftable in late rounds.
